Opera Solutions Research and Data Analyst - II interview questions

5 Rounds - 1 Written, 4 one on one. Already consider profile as very basic so If at all you know the answer of their tough question, they wont listen, just ignore. Very disrespectful. No professionalism. Rude interviewers and seniors leaders are the worst. No privacy when it comes to background check. "Give interview at your own risk, because this information is going to be leaked in your company the very next day"
